get-exchangeCertificate show blank ex 2019 last updates
Hi, I get-certifcates and show blank [PS] C:\Windows\system32>Get-ExchangeCertificate Thumbprint Services Subject ---------- -------- ------- I renew with MonitorExchangeAuthCertificate...
- next day i again get certificate and looks good solution wait after operation renew cert OAuth
I reproduced a very similar scenario in a lab recently, with one important difference: the Exchange Auth Certificate was already present, valid, and MonitorExchangeAuthCertificate.ps1 reported that no renewal action was required.
The useful clue was in the Exchange Data Serialization logs:
HmacCryptoProvider.HmacProvider:activeKey==null
Get-ExchangeCertificate started working once the certificate activation window had passed. This also helps explain cases where the Auth Certificate is renewed successfully but the cmdlet remains blank for several hours before recovering.
I documented the tests and the UTC/effective-date behavior here:
